Analysis of Thermo-Hygrometric Conditions of an Innovative Underwater Greenhouse

Nemo’s Garden® Project aims at creating a green, alternative, and original agriculture system based on underwater greenhouses (biospheres) developed for areas where plant growth is difficult in the terrestrial environment due to climate conditions new global warming issues. Experiments were designed performed measure thermal hygrometric behaviour inside biosphere; simple theoretical model was analyse temperature humidity of air biosphere dynamic interpret experimental observations. The main findings this research were: (i) photosynthetically active radiation measured 25–30% that sea level, (ii) relative showed cyclic daily variations permitted water evaporation/vapour condensation process, allowing self-production irrigation, (iii) results given by lumped-parameter good agreement with experiments.
